Where do you get f4i engine rebuild kits

[Greenhornet347]

I'm doin a frame swap on the junk f4i that u got and while I'm already there we decided to rebuild the motor...where do you get the rebuild kits at...anything helps thanks

They don't really make rebuild kits like they do for dirtbikes. You just need to order all the OEM replacement parts that you need. I don't know of your skill level but be warned that it isn't a job for the inexperienced. If you're not very confident that you have the skills you could be wasting your money and the money might be better spent on a low mile used motor

What would it cost with oem piston rings bearings.

[hypermike-gba]

Your looking at over $200 right there. I rebuildt two 636 motors and all parts cost me around $650 for both. shit aint cheap.

Just check compression. if it good then dont worrie about.

Well I'm not exactly sure if it is the motor..Im gonna do the compression check tomorrow..it's running really rich and there's visible white smoke..it revs really good but stinks like fuel..if the motor isn't fucked that be awesome..any ideas what it could be?

Black smoke is fuel, blueish smoke is oil, white smoke is water.

Headgasket?

Compression test will tell you that. Warm up the bike, then tear it down. Do a dry compression test and record your results. Then if any of the cylinders are out of line add ~1tbsp of oil to each cylinder and repeat. If the compression goes up on the affected cylinder then more than likely yeas the headgasket is bad. Though it coudl also be the rings. Which a leak down or blown by test will give you a better indication if it's the rings or headgasket though if the smoke isn't bluish you chould be good. Also the white smoke should be coolant and a lot of times can give off a bit of a sweet smell coming out the exhaust as it burns up.

i swear to god you people are fucking retarted this forum is filled with threads that start out with questions that can easily be anwered by google or just calling a shop........ you seriously asked how much will it be with new piston rings call a fucking dealership and they will tell you quit wasting everybodies time with these stupid questions.................and Fyi white smoke can also be oil have you ever seen a bike smoke that has the kleen air mod done to it????

If u can't tell the diff between the bluish grey smoke of oil and the white smoke of water/coolant the smell will help you. Oil smells more like burnt plastic, coolant dose have a sweeter smell to it. Or u can just check ur oil and coolant and see which one is low...
