For now yes. Soon ill get some slingshots and a pipe.

Can't seem to find fcr's at a good price.

what kinda paint is it? i used rustoleum, and it gets soft when the motor is hot, just to warn ya,.... like it never cures, just gets soft and rubbery

[Mekanix]

High temp powdercoat.

High temp powdercoat.

Does that not hold in to much heat?My engine is base clear and it feels like it gets a little hotter than it should.The 569cc GS engine I'm building will be high heat engine paint.

Stephen, look for 2 FCRs that are 37mm from 250 four stroke dirtbikes. You will have to get a custom 2 into 1 throttle cable made but that's no big deal. Those carbs go for 200 & less on EBay. Just find 2 from the same model 250. Ray.

be careful what carbs you get , lots of those have electronics , im sure there is something out there

actually it would be nicer just blasted aluminum ,and factory black, paint does hold in some heat, and you dont need to worrie about touching it up

The only electric anything on them is a TPS & they work fine without them connected to anything. Ray.

The guy that I am working with to build my 569cc has a set of 36 FCRs from a snow machine.We're gonna break in the engine with a heavily modified set of 36mm GSXR carbs.

the electric carbies cost more , and isnt used for electronics, so why bother ,and waste money was my point, there are tons of carbs out there you know

None of my carbs are electric or electric operated.

On eBay they are all priced about the same & the newer the make the better. PERIOD!!! Ray.

You guys already know this I'm sure, but I'm just stating it: the later GS500 carbs (with the TPS) are "3 jet" carbs. When was it? Around the year 2000 that they swapped? They added a mid-main jet for smoother / better performance.

Kind of a moot point though. Pretty much any modern carb is better than stock from the early 80's.

Anything with TPS would be good from a tuning standpoint... get an AFR setup and the TPS will help no end when collecting that data.

Go to www.wbo2.com and you can have a kit version AFR setup with half an hour's data logging and external display from $AU279.90... including the new type Bosch LSU4.9 sensor... make up a sniffer pipe for the sensor if you don't have a bung in the pipe and all good to go!

Or...............








you could just delete the TPS, RIDE the bike, do 4 or 5 plug chops, & jet it without the added expense of a bunch of unnecessary extra electronic crap on your bike. Ray.
