Carburettor Boring & Flowing by JK Tuning & Race Development
These are some of the modifications required to use the PWM carb on Motocross applications. The bellmouth extension enables a perfect match to the standard airbox.
	Here's some development work we have been doing recently with the 2001 Kawasaki KX85. The carb work is part of an excellent tuning package we can offer. So don't get left behind on the grid, join the queue to get that leap forward!
Even this ageing PJ carb can be transformed to turn out good results with our modifications, there are a number of tricks of the trade to be considered when setting these and PWK carbs.
	This particular modification is one of the single most cost effective and worthwhile improvements that you can do with a standard or tuned motor. It will noticeably clean up your low to mid range throttle response. Combined with our cylinder and head work this will ensure AWESOME results.
We can supply new PWK and PWM carbs and also all the jets and needles you should ever need . We can supply carbs modified from new, the bore size should be carefully selected and is entirely dependant on its intended application .
	For carbs such as the KX60 and 65 we have some additional bellmouth mods which can really sharpen up the throttle response. Using the carbs coupled with our porting mods we have already had excellent results this season.
Here's a Keihin FCR flat slide carb kit to suit the LC4 range.
