Hello All, I'm new to the Badweb, but in dire need of some help. Recently, I converted my 1999 X1 from 1200cc to 1450cc with the help of NRHS. The motor is sweet, STD heads, Carrillo Rods, mikuni 45, etc. Huge improvement over stock. But the handling is shot, the bike woble through every corner, and tries to stand up in corners more than before. I have gone several times through the reasembly procedures and cant find the source of the problem. I have checked and replaced the following: Isolators front and rear front to rear wheel alignment suspension settings tire presures Tie rods vertical and horizontal axis alinment between frame and swingarm/engine unit. I am currently running a penske rear and reworked showas forks, front michelin pilot and rear D208ZR stock sizes. Can anyone help???? If I keeep putting any more blind hours into this bike I will loose my marriage. Thanks.... | ||

Did you reinstall the washers that go under the rear isolator bolt heads? | ||

Hi Blake, Thanks for the response, No. i did not install the washers, but i did install Swing Arm Isolator Stiffeners that come with longer allen bolts, but no washers. What do you think? Regards,  | ||

Don't mix brands of tire. The profiles won't match leading to weird handling when leaning. | ||

Could be the tires, guess i'll have to go out and replace the front. What brand tire helps most with the standing up while in a turn problem?? thanks | ||

That's a profile issue and I would recommend a pair of Pirelli's using a rear tyre size of 180/55. That said, I don't believe your tyres are the issue, but whatever you do next if you go down the tyre / wheel route it is imperative you eliminate them from your problem. The only way to do so is to take the wheels with tyres (remove no pulleys or discs etc) and spin them on a dynamic balancer. See how much, if it all, they are out of balance by. If it is a big enough amount it will be obvious. Whilst the wheels are spinning it would be prudent to do a visual inspection and note whether or not the tyre is egged or the wheel is buckled. Don't change your tyres until this is done and you or someone you know who knows their stuff is satisfied with the results. Rocket | ||

Hello All, I went testing today... I inflated the tires to 40 PSI, and she handled much better. By the way, the tires are new. What is the recomended tire presure? But before arriving home, I ran into another problem.... At a stoplight, i did a full power launch and completely shreded the teeth on the secondary drive belt.... Maybe too much power, guess ill have to convert to chain drive. Its funny, every time i fix something, some new problem pops up. Once again, thanks, the support on this bbs is invaluable. | ||

I doubt it was too much motor for the belt, they are TOUGH. You may have had it a bit too loose. The should be run loose but not too loose. How many miles were on the belt? How old? I have had mine too loose oy 00 M2, it jumped teeth when accelerating hard in first gear. Felt like a "jump and catch". I tightened the belt a bit and it went away. also, check the teeth on your front pulley, if it's worn or sharp that may have been part of the problem. Let us know what you find. Brad |
