Thats stock jetting. I would have to say your on the lean side for sure for the mods you have. you should be good with pilot but I would go up to a 270-280 main. Do some plug chops and up or down on the mains from there.

With the mods you have you will be good with just running on 93 pump gas. Running stright race gas could lead to detto and a rebuild. you could do a mix but even at that you will notice little if any difference. But just for shits, whats your compression and dome size?

To give you a better starting point on your jetting, post your elevation and temp and you never said if its stock bore, need to this. As far as price, K&Ns are pretty much the same no matter where you get them.pod filters will give you the power gains, but do a little shopping some places will throw in outwears,and there is a post on this site that will give you step by step on how to mod your current stator for +4 timmimg.

Thanks guys.pretty much looks like you get what you pay for. The boss looks like good in quality and price, think i'll go with that. thanks again.

Has anyone on here bought a cheap oversized radiator.$90.00-$130.00 off ebay? If so how have they held up?or is it just worth spending the cash on a good one.

Whats your elevation,what size pilots, whats the temp, have you checked for air leaks, bad o-rings on the domes,did you do a carb sync????????????

You should be alright wires.charging is around 13.5-14.0 volts. I would run an inline fuse with it depending on wire size. I'm sure someone on here that has done this will give more and better info.

I believe 8mm will fit with some forcing, but 7mm will work . why do you want to replace the wires???

no. he's saying try a wider clamp on the filter. you also might want to try and scuff up the outside of the carbs with a light grit sandpaper to the filters a little more bite. I also run pods and never had 1 fall off.

Thanks for the feedback, I will let him know. Thanks again.

Has anyone in here ran a namura piston? if so how did they hold up? I'm rebuilding a 400ex motor and the owner wants to try one out. I perfer to run wiseco but the cost of the namura piston fits his budget a little better. Thanks.

When you put your idle screws in did you file the casting down on the carbs so that screws are able to move the slides up and down so you can adjust the idle?

thanks, she is booonerific.

their are 2 vent lines coming off the case 1-is at the back of the motor on top of the case, and trhe other is on top of the clutch cover right hand side of the motor. they are joined together by a "t" then routed up to the steering stem. i would those hoses off and see if can blow through them. double check your case oil and make sure its not over filled. 2 quarts MAX.
