TP107 Top end rebuild ??? with pics

[Chippy Chad]

I was looking for a little opinion and direction on my rebuild. Originally I was

just fixing base gaskets but it looks like I need rings. Does anyone know where

I can get some? Pic #2 shows a rocker cover bolt that I had to hack up two

allen wrenches to get out. How can I torque this when I reassemble? Pic #3

shows two gaskets that I don't have, I am assuming these are specific to

Edlebrock heads. Pic #4 is the gasket set that came with the bike and pic #5

is my progress so far.

My wife is gone for 4 days so instead of doing this in my well stocked shop I

set up in the garage so I can work while the kids are sleeping. I just knocked

them out with some venison burritos and I am headed out to finish the rear

head and pull the jugs. I really appreciate any help!

Got the rest done, is this a lot of blow by for a bike with 13k? I would like to

hear any opinions on the piston wash.

How do the sides of the pistons look? is there any blow by past the rings? are the pistons wearing into the cylinders? I am in the middle of doing a top end on my bike right now, I am no expert by far but the tops of the piston tend to be pretty nasty. I replaced my pistons due to wear on the back of the piston. Just figured while I was at it might as well. I called S&S and bought the top end rebuild kit, the kit they sent me included new gaskets. Personally I would not re-use the gasket as a matter of fact I was told not too. others may chime in on that.

My piston skirts and cylinders look great, no scuffing. I was under the impression if you

don't get an even burn that it's blowing by. I have some clean edges and a lot of black crud

build up that I was assuming was burnt oil. It would be great if I don't need rings!

While you have it down might as well rebuild the top end...have the heads done and bore the cylinders .010" over and a new set of pistons and rings...I spent around $300 for my local machine shop to do the machining, when I did the top end on my 107"

Pictures don't look unusal to me. Definitely go back with new gaskets and I prefer the multi-layered head gaskets. Depending on your budget make the decision to bore and re-ring, there wouldn't be a better time though since you already have it tore down.

Boy you are definately running that thing rich!!!!

Before I pulled it apart I thought it was too lean? If I stab the carb between shifts it

coughs through the carb sometimes. This gets way worse if it's really cold out so I thought

it was lean.
