Carb setup Adjustment for Cb750 with 836 Kit

(1/2) > >>

MeilakJ:
Hi All
I need some guidelines please

I think this subject might have been discussed many times.

 I have just upgraded my bike with an 836 Kit and when i start to accelerate bike misses out abit then ok. Also on idling its ok.

What set up carbs as in Jets and needle position and air filter would you recommend I start with ? The current jets are 40 and 105 and needle in middle.

Also from were is a good source to buy the Jets?

I would like to keep the stock air box since the bike has just been restored. Ive read that a K n high flow air filter would also help?

I know that not all engines are the same but a guidline were to start would be great.

Thanks guys

I have a 736 that's running 138 mains in PD41A carbs (pod filters and 4 into 1) it runs fine with no flat spots, I'd be tempted to go up a few sizes on your mains, as always check your float heights are correct, fuel level is vital to carburation, what colour are your plugs?.
PS NRP carbs are a good source for your jets and advice.

I am running a standard compression 836 kit (cruzinimage) with standard airbox and standard exhaust on my K2. I'm running standard jets (I think its 110 main jets). On the CR750 road bike I'm building I have the same 836 kit but will be running 4 into 4 CR750 straight through exhaust and standard carbs with foam pod filters - that will be a different proposition!

Hi Phil ,

That is exactly my set up,

Did you need any needle adjustment ?

Thanks

philward:
My needle is on the middle setting - it runs very slightly rich (slightly darker sandy colour) but not that it seems to affect the running. Air screws on 1 turn out. Hope that helps - good luck
Phil
