Newbie from Illinois with ?'s about 4mill

[TUCK]

Hi everyone you guys got a great site here. So I just picked up a 2002 Banshee with the following mods.

vito's 4 mill kit, shaved head, cylinders are on there third bore with wiseco pro lite pistons, fmf fatty pipes and silencers, k&n filter, lightened flywheel, barnett dirt digger clutch and springs,and of course jetted. ac nerf bars, msr dominator handle bars, and ac front bumper.

I acquired the bike in a trade. I traded a 86 250r,no title, with just a fmf fatty pipe and jet that i payed 1300 for it with a twisted off crank key and bad cdi and way overjetted. So I fixed everything and had it running good. Then a guy that must have been a complete idiot offered me the straight up trade for the 02 Banshee, with title, and of course I was all over it with the mods it had and the value of my bike compared to the Banshee. The guy kept burning up the pistons in the Banshee because he had it way lean. It is fixed now and the bike runs awesome but I WANT MORE POWER!

So here are my questions.

I feel that there is a lot of hidden power in this bike and I want to bring it out, so all questions, comments,and concerns are welcome.

Keep in mind I only have 1300 bucks in this thing now so I should be able to throw plenty of money at it and still be able to sell it for what I got in it.

1. There is no spacer plate on the bike and I know he didn't have the head reshaped......I don't quite understand port timing but this is holding me back correct?

2. The previous owner did not have the cylinders ported and I know from what I have researched on this site that this is definitely holding me back with stock porting.

3. What other simple mods would make this thing rip harder.

4. What is my bike worth with the mods listed?

 

Thanks, TUCK

 

Here is a pic of the 250r that I traded and the 02 Banshee I traded for.

If there is no spacer plate, and the head hasn't been rechambered, then it doesn't have a 4 mill stroker crank. could have a 5mil longrod, but not a stroker.

well the guy said that it had a vito's stroker kit and he couldn't remember if it was a 4 or 5 mm

I am still waiting to get the motor paper work from him

upon examination there is some kind of metal plate under the cylinder it appears to be about 1/64 of an inch or so. pics are not the easiest to see but there is a gasket,spacer plate,gasket and then the cylinder

Yea, i looks like you have a spacer plate, so you got a 4mil. The plate will not be very thick seeing as how the piston only comes up 2mil higher. Plus you have the thickness of a second gasket down there as well to raise the jugs.

 

If you want to make power, take off the jugs and send them out to be ported for the 4mil and lose that plate. You will also need to have your head relieved for the pistons. BUt the bike with a port job will be night and day difference if you have someone like F.A.S.T. or Herr open her up. Also need bigger carbs when you have it ported. Then hang on, might want to put a +4 swinger on as well, depends on the porting and type of riding you want to do.

 

Good luck, have fun.

my eyes must be going but I see no spacer. Also mentioned is a 1/64 plate. That is less than a half mm and you would need a 2mm plate there. I have strong suspicion you got hosed on the 4mm. Possibly a 5mm long rod but no stroker. The next logical step is porting. I would pull it apart anyway so you know the condition and level of tune.

The last picture you posted looks like a spacer plate, bbut with the quality of picture hard to tell. The plate would have to be around 2mil thickness, need to measure. if not you just got long rods with out the stroker crank, and different pistons, which really gains you nothing in power.

I am absolutely positive it has a spacer plate, I know it is hard to tell in the pics with my crappy camera but it is there no doubt.

Then get rid of it and have it done right. The spacer causes problems with port timing and flow. I will not install them on any customer bike, even if they ask for it. just not a fan of them.

PORT IT!!!!

It will be the most impressive gain you will see for your money.
