Nevil’s Bike Suzuki DR650 SE  “Twiggy”
As I bought it November / December 2011
Meet 'Twiggy'. Why is it called Twiggy? Because it's a lot thinner than my BMW R1200GSA as well as well as being a lot thinner than my previous bikes. It really is a lovely bike but it's going to stay in North America where it can be fixed easily if it breaks down. There aren't too many BMW "doctors" where we'll be going. The simplicity of the DR and also Ulf’s XT600 make them an attractive choice for crossing Mongolia and Siberia where there aren't too many motorcycle garages. Also they are a LOT lighter and we're not getting any younger (at least our bodies aren't anyway) so when we crash, drop or stall them ...which I'm sure we will, they should be a bit easier to deal with. Oh yes, the parts are a lot cheaper too. All that said, I'm considering the following for the DR : 1. Upgrading the stock suspension front & rear. The factory stuff is very soggy and needs to be stiffened up a lot. I am currently looking into Cogent Dynamics rebuilding my rear shock absorber and sending me the DIY kit for my front forks. Remember, we're doing a lot of rough roads on these bikes. 2. Replacing the existing fuel tank with a 6.9 gallon Safari Tank. It's nice to have the range if you need it. Also, you don't have to fill it every time if you're just travelling between towns. 3. Replacing the seat. I'm entertaining the idea of buying the DIY kit from ProCycle USA. It looks fairly comfy and you can fit it to your stock seat pan. 4. Wider foot pegs. Need to be able to stand for a few hours every day and don't want to kill my arches! 5. Small windscreen. The DR doesn't have one but once again, ProCycle sell one that you can attach to the headlamp cowl without too much bother. 6. Fork brace. I don't want the front end flapping about like a rogue supermarket trolley wheel on gravelly and rocky roads. I think the Happy Trail fork brace will be the one because of its simplicity. I also like the fact that it bolts together and thus can be fixed if I can find a welder. 7. Handle bars. The stock ones are a bit weak. Fortunately my friend Grif came over the other day and gave me a set of Moose racing bars complete with brush guards and.... 8. A bash plate for the engine (see photo below). Thanks Grif.... I really owe you big time! 9. He also gave me a magnetic oil drain plug too. 10. Heated handlebar grips. I got spoiled having them on the BMW and now can't live without them! I don't like the idea of a heated grip being mounted to a plastic throttle sheath though. 11. Aluminium throttle sheath. 12. Happy trail Pannier kit & rack. I like the Happy Trail product and it faired well on the trip last year on my BMW. The new ones will be a either 71/2 inches wide or 9 inches wide. That depends on how much stuff I intend to carry. The list I have is almost endless but I really don't want to bore you too much at this point! The items listed above are there for starters so watch this space to see how I get on with buying and fitting. Priority #1. I need to raise the bike on its suspension though. Somewhere in the last 7 years, someone lowered it by the factory method (upper bolt hole on the rear shock absorber and spacer removal of the front forks) photo below. December 2011.....I need to find somewhere to work on the bike because at present I have no garage, live in Canada and it's WINTER! So, if you're in the Canmore area and want to donate a bit of space to a quiet reserved guy who just wants to strip his 650 down and make your premises look like a yard sale then please contact me :) Please watch this space for more updates. Also please feel free to offer advice on the bike stuff or critique my blogging style if you want.
Canadian winter March 2012
Canadian winters are a good time to work on your bike.......just don't expect to ride it for 6 months! Please bear with me as this post will be a bit technical but if you're reading this because you want to prep your DR650 there might be some useful info. Christmas came and went in the blink of an eye and before long I was back working on the DR. The first task was to fit the bash plate, new handlebars and MSR brush guards. My choice of hand shield was basically the biggest lump of plastic I could find to bolt onto the brush bars. MSR provide such a thing and so far they have certainly managed to keep the cold winter winds from freezing my hands. The engine bash plate was easy enough to install and during this process I drained the oil, installed a magnetic drain plug and put some cheap oil back in. Why cheap oil? Basically i will run the engine for about 1000 kms and drain the oil out again to see what state it's in. By inspecting the magnetic drain plug I should get an idea of how the engine is wearing. Rear shock absorber. There are many products out there for the DR. I chose to go with a Cogent Dynamics rebuild and restore the bike to its full factory height in the process. The turnaround time for the rebuilt shock was a couple of weeks and pretty soon I was back in the workshop installing a shiny new item that I hope will stand the punishment of Mongolian roads and the Road of Bones with me and luggage on board. Old shock absorber (picture above) ...note the two holes at the base on the right. This is the factory way of lowering the back end of the DR. Shiny, new and with some extra adjustments added in lovely anodized red (picture below). Basically it was fitted with a new gas bladder, cogent's own internals and an 8.1 Eibach spring. According to Ric at Cogent this will be good for me (185 pounds) and around 70 pounds in luggage, tools, tyres etc. Front forks. Hmmm.....what to do. The front end is way too squishy and dives heavily under normal braking. I've spent a lot of time on forums recently, especially the DR forum (DRRiders) and there appears to be a growing fanbase of Intiminator users out there. Ricor Racing Intiminators are basically a valve system that one can install without having to remove or drill out the dampening rod. Just install under your spring on top of the damper rod and screw it all back together again. Fill with 5W oil and ride. Actually it's not quite this easy because you really should set up your preload according to your preference by manufacturing and sizing up spacers on top of your springs too. Many people claim that you don't need to replace your stock front springs for this either. I will give this a try....watch this space for a report. Tool tube. I built this a few weeks ago from some 3 inch PVC pipe and two pressure bungs.The idea was to fit it in place of the existing stock tool tube to gain more carrying capacity. Everything was going well until my mate Grif bought me a new shiny alloy tool tube for doing some renovation work at his house. I will be fitting this new item very soon! Stock Suzuki tool tube at top. My home made tube in the middle and the cavernous new storage at bottom! Grip Heaters. Yup... I need them. For the longest time I considered Oxford slip on heaters but in the end I went with Happy Trail's kit. This includes a set of heaters, a toggle switch all the wiring and a free set of gel grips. I also elected to buy an aluminium throttle tube to replace the plastic one on the DR. I did this for two reasons, 1. I didn't want the new heaters melting the plastic of the stock tube and 2. Suzuki glue their grips on with REALLY strong glue. I'd rather lose my sanity in a more complicated way...not wrestling with a set of cheap grips!
“Twiggy” becomes a RTW-Bike Spring / Summer 2012
Toggle Switches. The heated grips come with a toggle switch to control them. I also want to install a toggle switch that will cut the power to the headlamp and save generator time when I need to run the heaters and charge stuff like camera batteries etc. There's not a lot of room behind the small fairing for this so I've elected to mount a small plate to the left handle bar clamp that will contain these switches. see below. I have a feeling I'll be revising this design but for now it will do. Rear wheel ...Especially the Sprocket bearing. The DR is famous for eating the rear sprocket bearing. Basically it's a combination of a nasty OEM bearing that only has one dust seal on one side and the cush-drive rubbers wearing and getting sloppy. My advice...replace the rubbers with new and install a bearing that has a dust seal on both sides. Don't forget to pop the dust seal on one side, pack it full of grease and replace the seal again. Bearing factories are very miserly on their grease application. So far so good. I did actually manage to get out for a couple of rides. At this time of the year in the Canadian Rockies that's a real bonus I can tell you! So far I have only racked up about 130kms but spring is on the way! The small 'touring' screen can just be seen velcroed to the headlight surround. The Safari Tank donated by www.safaritanks.com Twiggy with her instant girth gain. Still loads thinner than the BMW Warthog though! A quick strip to replace the piston with a Wossner, the clutch with a kevlar one. a new timing chain and an aftermarket centre stand! The ProCycle Gel seat cover (on the right) Wolfman Enduro tank bag, Aerostitch tank panniers, and a piece of ally strapped to the back to support the holdall whilst I take a trip to Happy Trails to get my luggage system. Mirrors set to spot low flying aircraft??? My new Happy-Trail luggage system.
Ultimate Perfection Winter 2012/2013
Hi folks, Well it’s been a while since I added some material to the website. The month of February has been very busy for me with all the final preparations for Twiggy (the DR650) and plans for flying her out of Calgary to the UK to start the trip. Wow! I cannot believe the rules and regulations that have now been imposed on freighting a motorcycle recently. The paperwork is like doing a small degree. Anyway, last summer saw me receiving all the Happy Trail sponsorship stuff from Boise Idaho and then I spent the whole summer putting the panniers to the test on some of the most rugged trails through the Canadian Rockies. The results were good, it all stood up to the test so I feel confident that I have the best product for the task at hand. The winter was a different story entirely. I spent my time stripping Twiggy down and working on all the little items that needed attention. For example, I needed to install a fuse block panel under the seat to power my grip heaters, LED spotlight, accessory cable and charging indicator light. This in turn was switched by a relay that is activated/triggered by the rear license plate light when the ignition key is turned on. This means that no accessories will turn on unless I turn on the ignition switch. Battery drain minimized :-) I also drilled into the top box on the bike and ran a power cable through to the inside, silicone it all up and now I can charge all my cameras and laptop in a dry environment using a cheap inverter. After adding a heavy duty rectifier from a DL650, the output is sufficient to charge my 45 watt laptop, run a 65 watt headlamp bulb and grip heaters well. I also received a very generous offer of sponsorship from MOTOVAN.COM. These guys do everything for power sports and so within a few weeks I got tires, chains, sprockets lube tools, air filters and filter skinz delivered to my door. All parts have now been fitted and tested. I particularly have to sing the praises of the filter skinz. They negate the need to oil your filter and thus you can wash /replace both skinz and filter with ease. Along the way, a decision was made to fit the Suzuki GSXR1000 Titanium silencer to Twiggy. This was a discussion between myself and buddies Grif Griffith and Jim Smith. I wasn’t convinced this would be the best for Twiggy because she had performed so well over the summer with the standard exhaust and jetting and I didn’t feel the need to change anything that wasn’t broken. Jim and Grif convinced me otherwise stating that many people had already done done this conversion and no one had experienced bad results. So…..Twiggy is now fitted with a Keintech midpipe, titanium can and a 1.55 main jet in the carburetor (I believe stock is 1.44). The top of the airbox needed to be cut out as per the jetting instructions (they actually give you a template at ProCycle). I didn’t like the idea of the open airboxbeing totally open to all the dead moths, dried leaves and beetles that could potentially get in there so I siliconed the edge and adhered a piece of mosquito mesh to prevent stuff from getting into the airbox. “but what about water getting in Nevil….how are you going to cross rivers?” Simple. If the river is too deep and has a likelihood of going over the top of the airbox I won’t go through the river at that point or will find another way of getting Twiggy to the other side. I’ve done it before and will do it again :-) Last weekend saw some very mild weather for a Canadian Winter and the snow melted off the roads well enough for me to go and test the newly built Twiggy out on the open roads. Wow! What a difference the exhaust and jetting made! This, coupled with a 16 tooth front sprocket made highway riding seem very easy. The Doubletake mirrors do vibrate when starting out and going through the gears but settle down to normality once you’re up to speed. Mirrors on a thumper will always do this to some extent anyway. Personally, I really like the Doubletake mirrors because they are fully adjustable and will fold in if you take a spill. My home made windshield extension appears to work quite well. I rode the 35 kms back home against a high wind and nothing folded in or flapped around. More testing is required before I commit to this size of extension though. I will naturally give you a report on fuel consumption in a few weeks when I fill up and go out for a long day.   Conclusions:- Everything I set out to repair and make ready has been done. The bike appears to be running well but will need more testing yet before I’m confident that all the changes made are good ones. Watch this space for more news …………
