https://www.monkeybike.co.uk/acatalog/Takegawa_Hyper_CDI_Unit_for_12V_Monkey___CRF50.html

what do people reckon? its the correct fitting for the honda cb harnesses, i used to run these on the monkeys and would let you rev all the way up to 13,500rpm with very usable power all the way. made my honda nice 127+R pull like a train.

any thoughts as to weather its worth a try?

Its probably a Honda CB125TDC CDi unit, or based on one! I doubt it will make one jot of difference. TD-C isn't restricted in the ignition anyway.

Honda Part No. 30410KC1008, used accross models and 'Benley' range, and stock on both UK 'Reduced Effect' TD-C and the Full Power Beligain model.

Lets the bike rev 'free' and they will go off the dial well past 14K without much encouragement; 13,500 would actually be an artificial rev limit!

AFAIK 'Smart' money tuning monkey bike motors was to fit a 2nd hand Benley or CB CDi unit, rather than unreliable Chinese 'Performance' one....

ok cheers dude, was trying to get hold of a cb125t camshaft the other day, phoned and e-mailed a few people and was told that the cb 125tdc camshaft has the same part number as the cb125t version. was it a european version that was different or is it something else that made them full power?

They were de-tuned with various different parts. Which countries got 'full-power' and which got 'reduced effect' depended on local legislation; there wasn't a UK bike and a Euro bike. Germany I believe got both versions, as did Ireland.

1977 CB125T, though lists camshaft Part No. 14100399305
1982 CB125TD-C lists camshaft Part No. 14110399700
1988 CB125TD-J lists camshaft Part No. 14110KC1730

The one in the e-bay add from Riders, Snowie linked is a Lifan part, equating to the cam used in the CB125TD-J that had CV carburettors. Unless you want to pay a couple of hundred quid of a cam, its probably the best there is out there.

You wont get a 14100399305 cam; it is discontinued; 14110399700 is listed as its 'compatible replacement', probably why you were told same part number.

so is the tdj version better than the tdc version? and i guess the only way to get a 't' version would be to get a whole engine when one comes up on ebay?
