Hi ,

Today I bought my first aftermarked exhaust and after a long seach on the web and on the forums a actually decided to buy a Duncan racing exhaust .The DMC exhaust is the same !!Because I am from belgium , and they do not have so many stores that sells aftermarket parts I know the mighty amerika does :-) .So if somebody can help me out I can order the correct jet .

Now my question is :

- Does anybody know how I have to jet my carb with a stock airfilter but with a vented airbox lid and a WB High rev C.D.I Unit ?
- Does anybody know how I have to jet my carb with a K&N filter and a vented airbox lid and a WB High rev C.D.I Unit ?
- If you put a another jet do you also modify the needle or do you leave it stock..

I hope somebody has expirience with this kind of pipe ....
Please help me out ....
Tnx

Kenny
