10/15/2024 10:24pm Thanks for the detailed info, i will let it go :-) Still looking for DG head and performance pipe options, even considering modifying one of my later model pipes to try and see how they go from measurements they are very close but slightly larger diameter and gradually increase in diam instead of const on header so maybe be good.
gavan Started a new thread 1980 yz125g head vs 1980 it175g head
10/14/2024 3:19am Can anyone advise the difference between 1980 yz125g head vs 1980 it175g heads. If it will fit then i think i can reshape if need be. It looks like the same and have asked questions around, if you have a 1980 it175 head or cylinder perhaps you can measure it up and I can compare to my 1980yz125 measurements. Hope...

gavan Added a reply to Possible group buy: 98-02, 03-04 CR125 replacement cylinder with corrected port and transfer layout
1/30/2023 9:09pm I ran 98 pump, then with octane booster and then with Avgas a low lead 100 octane. The avgas was best. Ben_Tukes 2ml over probably gives added mid range which i would do but stuck with it being a 125 to be the same as my old bike and able to compare to my yz125, the yz definately pulls like...

1/24/2023 5:02pm You note that you are making port programs etc, can you calculate the difference when ports are lowered by 0.5 and 1.0mm as done by these professional tuners.

1/24/2023 4:55pm Hi Ben, I have the cylinder back, i can tell you the bike is very easy to ride and close in power to my yz , i do have to confirm that with another rider as maybe i was changing gears better but there was little in it. I used standard head machined by Pro Circuit and cylinder with vforce...

9/27/2022 7:50pm There is a lot involved in deisigning a new cylinder hoping it will be same as the YZ, there are other factors, pipe/ sliencer, crankcase, carb etc. It would be a pity to put all that time and effort in to find it does not work without the other bits. I am interested in what you are thinking and happy...

8/28/2021 2:05am I have an 02 which has slightly different holes for crankcase, i have an 03 cylinder near new that i will modify to fit so I can do the same with the cylinders mentioned on here. I would like to know what happened on this as I would like to get the cylinder onto my bike.

gavan Added a reply to 03 CR125 Pipes
5/20/2020 3:48am Is it possible the pro circuit pipe for the 03KX 125 would also be good if you cannot get a stock one... ? Thinking of putting it on an 07 cr125.
gavan Started a new thread Which CR 125 use RC valve or 2007 CR125 ?
2/27/2020 1:33pm I owned a 2002 CR125, no RC valve. I see conflicting statements from there on, I called Honda shop and they were no help. Can some one point to a genuine site and tell what has and does not have an RC valve, as I am looking for an 2007 bike , can someone show me 100% proof of what...

2/27/2020 1:33pm That is exactly what I needed thank you, I could see the RC valve label and had seen comments from owners that they all are the same as in same as 2004. Your explanation makes sense. Thank you so much.
