So my valve clearance became extremely excessive all of a sudden. The weird part is my bike ran fine before. I had taken it on its maiden voyage since my second time in the engine earlier this spring (~70-100 miles) and one thing I noticed was that the cam chain appeared to have gotten a bit on...

I ordered some banjo bolts from mikes because one of my originals sheared. The ones they sent me just start to thread but come to a brick wall and don't want to thread past about a mm in and I am not about to ruin threads. My copper washers also seem a smidge too small to fit against the base...

My walmart is out of the usual brand of 15w40 I use. I usually use Rotella t4 15w40. I dont want to open any cans of worms but I couldn't find a definitive answer about this brand searching the forum.

I may be over worrying... but I just want to run it by you folks first. Today I was showing a friend my work that I had been doing on my engine and I showed him the cam chain guide mod. He noticed something I did not. In my pictures he said my lock nuts may not be locking because my screws end...

Any ideas on a replacement that I could get at the hardware store so I can maybe ride today. This is the one on the advance side of the cam.

I finally got my engine together last weekend and I may (if I get the time) put it back on the frame this weekend. Before I do, is there a way to check oil flow before I put it back on the frame? I keep spinning it over with a wrench and am not seeing anything in the rocker box. Will I have to...

I know it doesn’t look pretty, but I did measure flare out to be about .01” does this look ok. I’m a bit anxious about it and for sure don't want it to pop on me. Let me know what you think. I used a homemade tool that didn’t work so well which is why it looks real messy so I then went and...

Sorry I’m such a worry wart and have to ask a million questions. I just want to make sure I do the little things correctly. Do the big O-rings that go around the cylinders get smooshed down in the groove or rest just above it? When I attempt to push it into the groove I cant get it to go in all...

first time ever installing pistons into cylinder. I can get my top and middle rings in... my oil rings are another problem. They don't seem to want to go in and the one time i got them in slightly it felt like I was about tear up my bore so i did not proceed to try and push them in. They seem to...

Hello for a second time in one day, Now I have a piston ring question. I ordered a set of standard size rings off of eBay. They come from XScycle out of canada. After receiving them I just did some more research and found a post where someone posted width discrepancies...

Hello, I am getting closer and closer to finishing up my rebuild. Today I was cleaning up my gasket surface on the head and noticed a bump on the gasket surface just above my exhaust valve. My head is nice and flat. (checked with a feeler guage) I must have done it while putting my valves back...

I just started lapping my valves. This is after 1 min or so of course paste. Am i doing ok? Not sure if this enough on course grind and if I should switch to fine.

I read about just buying standard 3/8 brass washers and stacking them 2 high. Would this accomplish the job? I just don't want to spend $5 a washer plus shipping when I could just buy those at the store. Any reason why one would avoid doing that?

Does anyone know if this part comes with the little master link in the picture? It doesn’t say in the description... If that is correct I should be able to just cut it wherever and link it back up for my top end rebuild? Will I need to buy that part separately? Here is the part link...

I decided to just hone it myself after watching several videos online. I didn’t want to pay someone for something that looked so easy especially when the machine shop was on the other side of town and he wasn't even sure he could do a cylinder as small as mine. How did I do before I move to my...

Hello again, I am struggling to find a machine shop that has the tools to hone motorcycle cylinders. I’m going to go see another one today or tomorrow whenever I get the chance. If they don't have the tools I was going to see if I could just buy the tool and let them use it, or even try it...

I was given an opportunity through a connection I have with a friend that works at an industrial supply company that I also worked at for a short while. It specializes in fasteners and I was going to seize the opportunity to order new engine mount bolts for an employee discount price. I will be...

i am a bit confused. I am measuring my piston skirts and cylinder diameter. My cylinder diameter is looking to be about 2.9504” and when I measure my piston skirt I am getting about 2.9502. This doesn’t seem right as I thought piston clearance should be about .002 and I am off by a factor of 10...

Firstly, I want to say a huge thanks to Jim for doing the write up on this mod. Jim also kindly gave me the hi-lok screws that he used to do this mod. He didn’t even charge me for shipping. Jim is a super nice guy! This is Jim’s write up that I followed here...

Hi all, Doing a top end rebuild and need to start cleaning up my parts. Question1: Should I avoid soda blasting gasket surfaces when I go to soda blast? As far as the head goes, should I pull the valves out and clean the carbon with a wire dremel before soda blasting? Or could the soda blast...
