Moto Compression tester

     

ok all need a bit of advice and drawing on all you experts out there...

I need to break down and purchase a Compression tester, I want to know what one I should buy if anyone has had experience with them.

there are a lot of them out there and they range from 18.00 to 250.00, I need them to work on all my bikes as well.

Bikes are as follows

2009 KLX 140
2003 CRF 450 R
2003 YZ 85
1996 CR 250
1991 KX 60

and my road bike would be nice FZR 600 1989.

Suggestions where I can pick one up for a good deal would just be a bonus.

Thanks
Scott

Just know that the compression tester won't really work on a 4 stroke with auto-decompression (your CRF). Otherwise, get something that will last.

POOP!!!! no worries ... I plan on a refresh for it every 2 seasons so no worries there... but the 2 strokes... is what I really want it for.

The problem is they range from literally 18.00 to like 300.00 when I was racing we used the cheap 18.00 one but we also had a lot of people around to help with it.

Thanks
Scott

Oh, and just make sure it has the connectors to fit your spark plug holes. 8mm 10mm 12mm etc. I used to know what the 85's were, but I can't remember.

The leak down tester is going to be better all around, and you can use it on your CRF too.

Hi everyone

I got this bike 8 months ago and it's not running smooth. Fitted new air cleaner, spark plug and FMF packing. Carb settings STD, but its still not pulling clean, so yesterday I removed the air screw and spring from the carb and now its GOOD runs like a beast, clean and smooth, start's first kick.
Just one Q: what the hell is going on with it????

The Craftsman model looks nice Scott, and I am going to check the Harbor Freight near our home for the one ya'll are talking about tomorrow. I need a model with both the compression tester mode and the leak-down teet mode combined since I have a 426 and my son has a YZ125.

VTR,
That year CR250R was really hard to jet and couldn't get properly jetted through out the range. I would post up the question in the Honda 2-stroke forum and let OSSAGP1 find it. He is one sharp guy on jetting and the CR 2 stroke line in general. Best of luck in getting her jetted. They are super reliable bikes and aftermarket parts are plentiful. It sounds like you have her pretty well tricked out already.

Merry Christmas,
Bill
