Honda / Re: Honda CR125 Top end interchangeability

« Last post by rocketfrog on Yesterday at 11:07:26 AM »

Acknowledged GMC, I have suspicions and an educated guess but it will cost me about $400 US to back myself on a hunch. Soooo, I was kind of hoping for a definitive, resounding confirmation before I click the Buy Now.

Cheers Jason

Thanks Geoff, great pics !! alot of moded MX bikes back then. I guess they were cheaper than the euros. Do you remember doing any suspension mods to the TT350?

Just updated the photo links, they should all work again now.

Wow, 10 years and I just realized I didn't reply to NSR

No Photos of Ricky, these are pretty much all I have.

Only vaguely remember the kart track, my times would have been poor as I was busy trying to stay upright.

Starting at the back its hard to imagine how you could have a good day on day one, it was just a big slopfest when I went through, guys always seem to get themselves stuck in the easy lines so going around them in the awkward lines just consumes time and energy, 300 k's a day of that shit was all too much for me

General Discussion / ebay calculated import charges increase.

« Last post by John Orchard on Yesterday at 10:16:18 AM »

Hi Guy's, l thought that when ebay started adding 'import charges' to the total purchase amount, l thought it was 10% but when l put stuff into my cart now it is calculating about 21%. Am l going crazy or am l now ceasing any purchasing from overseas?

Using toothpaste as a cutting compound reminds me of a young guy I worked with back in the 80’s, he had resprayed his car, not too bad a job for a first attempt from a metalworker.
He sprayed it one weekend and was going to cut and polish it the next week end after it had some time to harden.

He was telling us he was going to use toothpaste as a cutting compound as someone had convinced him it was better and cheaper. It made sense to me that it would be cheaper if you only wanted to clean up a small spot or something but to do a whole car would require quite a lot of tubes.

The following Monday he was telling us how he had to keep going back to the shops to buy more tubes as he needed way more than the 4 tubes he thought he would need.
Would have been way cheaper to just buy the proper product.

Mind you though, his car did have a nice minty freshness about it.

Your already onto the checking of head and base gaskets but the other one to consider are read valve gaskets and exhaust flanges but you always have to wonder if the part numbers are correct as there are a lot of common mistakes in the many web sites and Zedder etc.

It does look like though that the power valve mechanisms seem to be the same over a few years but the power valves themselves are one year only along with the cylinder suggests to me that they were more likely changing the porting specs more than a major revamp.

Kawasaki did this also in the late 80’s and early 90’s, they often changed the port tracts and the scallop shape in the power valve otherwise  the cylinders were the same.

I have no knowledge of your model but I would assume you could use a different year if you get the matching power valves to suit.
Beware though, my advice comes with no care and no responsibility

It will only make the models rarer when the countershaft breaks.

Honda / Honda CR125 Top end interchangeability

« Last post by rocketfrog on January 22, 2019, 11:36:26 AM »

Guys/Gals, I would normally search sites such as partzilla for interchangeable part numbers to seek the answer to the following question myself, however, my research has come up short.

Has anyone knowledge of a known Bolt on top end substitute for a 1992 CR125. For example do 1991 - 1993 use a cylinder assembly (inc power valves etc;) that will bolt up and work on the 1992 CR125 Bottom end?

I have seen ads for cylinders that state "fits 1991-1995 CR125" is there truth to this or not?

Usually I would check which parts are used on other year models and make a judgement based on say base gasket interchangeability indicates the same stud pattern on models using the same gasket for example, Piston interchangeability suggest the bore and stroke are the same one year to the next and so on.

In this case the part is discontinued and no supplementary information is available, so I need first hand Honda expert experience before I pony up for a barrel/top end that will not work with what I have.

Cheers
