    When I lived in Thailand, I added a rear HyperPro spring for my weight plus riding gear and anything else I might carry, also changed springs in my forks for my CRF250L-it had '97 CR forks, did not change any height at all, but cut my rear link by 1/2 inch to raise it for more travel, oddly, by changing the linkage geometry I felt it made the rear much better and added 1.25 to the height/travel, I wanted mx suspension. Am a firm believer in progressive springs, I used the L for traveling all over Thai in all sorts of terrain, just saying...

    I'm doing a top end rebuild and I need intake and exhaust valves.Are aftermarket (vesrah or similar) valves good for 650R or I must stay to OEM which are too expensive (especially Exhaust valve).
    If yes does anyone knows where to search in Europe for aftermarket?

    I never installed it so don't have any mounted pictures. Shouldn't be hard to install and hookup though.

    I bought it in case I went to a rally setup, and because it was an original team unit built for the bike.

    I'd consider selling it...you can PM me if interested.

    Hey guys-have the parts for a C-Fab estart that I just took off(really could not get it to work properly and has 0 miles on it) if anyone is interested. $300 but you pay shipping. Pm me and will have pics to show what I have-sorry, painted the aluminum red, but easy to clean up!

    Anybody find an exhaust plug for bike washing that will work on the large diameter (2.25") race reverse megaphone pipes? Everything I can find online seems to be too small...

    I have a 2.5" baffle core and haven't seen anything commercially that'll fit. I use a Pro Circuit tip that narrows things down a bit & their largest plug barely fits in that.

    You might have to look for something in the non-motorcycle market or make your own.

    Stock is 14/48, so a 14/46 would be 'almost' like a 15/48 that I've run. That would be a very good gearing if you are doing mostly two track, desert and pavement. Flowing, fast single track would be ok, but you'll notice a hole between 1st and 2nd.
    I kept the 48 rear and just swapped between a 14 and a 15 front. Easy to swap.

    Lots of discussion here:

    I like it. Was reading that page previously but wanted to double check. There is a good possibility I can get a good chunk of time off work and have been researching a bunch on the dempster hwy. It would be a hell of a ride on the XR from Colorado to the Arctic but what the heck. Currently running the stock 14/48 set up now but do not want to mess with the front sprocket set-up. But if it needs to be done, it needs to be done.

    I'd just throw on a 15th and see how you like it. 'Messing' with the front sprocket is easy, you can do it on the road. Be sure to put some moly-grease on the splines.

    15 tooth sprocket is a thing.
    Moly grease is a thing.
    Messing is not a thing.

    I ordered new sprockets for a trip on mine 12 years ago that showed up too late, so I rode around 2500 kms of highway with the stock gearing. It actually wasn't bad, cruised around 120km/h (GPS) pretty easily. I had planned to go 15/45, still haven't put them on. This summer I went to 13/49 for technical single track, might go back to stock or finally try the 15 front for dual sport use if I insure it again next summer and use it for commuting to work, 40 miles per day.

    Is the grease suggested? I just swapped my chain and sprockets the other day and I tried to look in the shop manuel if it had any mention of greasing the splines but didn't find anything.

    I went with 14/45 again. It gives me top speed of about 160kph (100mph) which is plenty for me. I have 110 chain length which allows to also use 48 tooth rear sprocket or something in between those.
