I asked K&T performance about circlp position and they said it dont matter.They have built thousands of motors so who do you believe?

[quote="maddog1927"]Maybe dyno port on the pipe? What are we talking about it hitting, the water hose that goes to the back of the cyl? quote] No on the older bikes the pipe goes way higher up by the air box and on the newer bikes lower about 6 inches. Cpi said all i would have to do is ro...

I called cpi and said they would have to send a pipe with out the rear section welded for me to rotate and weld . My bike is a 87 so do you guys think just by rotating the rear of the pipe every thing will line up. Seems a little to easy. My motor has 200* and 130* timing so is there another pipe th...

Who does a good round bore job with a deck plate? I got the octagon burn streak by all the stud thing going on not good lol. A web site or phone number would be great.

I dont see a digital set up?

What year of tree and forks,and what bearings and what else to convert to like a new 450 or 250? Should i stay with a 500 set up. My forks are toast making a loud popping noise and oil pours right through. I think i would be money ahead to update than to sink $200 or more rebuilding my old junk.

Anyone run pvl ignition on their 500? I use them on my drag banshee's and like them. I thought this would be an alternative to a cr250 ignition thats getting harder to find.

I have a 87 bike can i just order a pipe from like cpi,shearer and get one, or do they need a bike to make one on location? Im thinking about drag porting or a (liger cylinder),drag pipe, 50mm carb on alky. I tried a shearer pipe off a quad and holy crap what a difference. It had to make at least 10...

Wide band o2 sensor.

kehin dosent make a replacement seat. If you get it you would have to rob another one out of a different carb. Either buy a gravity carb or put a fuel pump on it.

I got like 6 39pwks from polaris snowmobiles. All wont work i dont see how a artic cat would be any different.

They got the brass choke adapter and angled down fuel inlets. And i believe 6.O slides.

The fuel needle thats hooked to the float not the one on the slide.

No the needle and seat is way smaller. Pull the drain plug out and hook the fuel line on it. It will barely piss out. It wont even get out of first gear and it will run the bowl dry been there done that.

Pull out the float out of both carbs and look at the seat orifice. Then you will see what i mean.

I bet those carbs wont work with a gravity fuel system. They are set up for a fuel pump. If your fuel inlets are angled down they are for a pump set up.

Upp makes them up to 50mm.

Who you talking about cp?

Dennis said upp makes the angled ones also.

Called packard and he said the 48 lectron on a rino or ds650 is the same carb we 2 stroke guys use just a different needle. They are straight bored and he recommended a 48hv with dual power jets for $385. He also said UPP makes a intake for the 48 carbs. Also he said 95hp with his porting and pipe a...

I got a friend that has a 48 lectron on his ds 650 quad that is for sale i think he wants about $250 for it. Are the lectron carbs the same for a 4 stroke and 2 ? I realize the needle will have to be changed but is that it?

Its in a stock 87 cr frame so angled. Upp makes intakes for cp industries cheetah dm cylinders (cr500pattern) so maybe they would make a few for us bike guys? Why 3 power jets? Dave moore makes power jets that will flow as much out of one and less air restriction. Oh and what air filter set up will ...

Looks good glen do you have any suggestions on gas jetting and what do i need to do to run on methanol? I have a few power jets laying around. :P Would drilling the dump tube to about .120" get me close? Oh and do you think having it bored out to a 45.5-48mm would run any better? http://www.the...

Called gss and they said get a hair dryer and stretch it. I guess 44mikunis will fit in stock boots after all.

Where do you guys get your intakes for big carbs?

Sounds bad azz! What carb and pipe are you running? Leaning toward loomis at this point.

I really think the biggest restriction is in the exhaust port flange area. Im trying a bigger flange and opening up the flange area to a saber size flange.
