Good stuff, think they run some Loncin's in Oz, seem OK, but I'll see what I can find out for ya! Will be good in a RGV150 chassis!
Have a look through this thread, might help! http://teammaddogracing.com/phpbb/viewtopic.php?t=310

I lked to look of the Loncin until I read that it is Chinese. I know it shouldn't matter but it does ...

Its ok, They are a complete direct copy of a specific honda engine. Like direct copy and are actually quite reliable.
Fishy has one in his bucket and he thrashes the shit out of it, i think he finished the endurance race tho! But then again my AX100 engine did too, with half the exhaust hanging off. In fact i was leading for the first lap!

Well, the Loncin is only an idea.
Ideally, I'd love to run a CB125 Twin, but they take a little too much tuning and you have 2 of everything. However, haven't ruled it out completely.
But we're definitely going with a 4-stroke, good for Nasty to come to grips with racing.

If I must be there, it will be in a nice 3/4 length number with pearls and gloves to the elbow. Oh and an Oriton purse for the half-time oranges (did I get that right?)

watch what you say I have the pearls!

Go the twin!
They're extremely reliable if you don't sail them too close to the wind

Bloody big and heavy motor with a wide crank, you need a fairly stiff chassis to make keep the engine from twisting the frame and creating understeer and instability.The stock chassis seems to work well enough but I wouldn't go lighter or smaller from there (been there done that!)

As for the Loncin, having ridden Fi5hys bike I can say in terms of power and torque whilst not being "flash" it's certainly makes good use of what it's got, and is easy to ride. Reliability will only be measured with the course of time.
The Honda GL145 engines were ok but they're quite suseptable to dropping valves when used in racing applications, so it will be interesting to see how long Fi5hys one goes in this respect.

Thanks for all of your feedback, peoples.

From what I've learnt, the Loncin's aren't that resilient, the CDI's don't allow the engines to go much past 10K and the clutch baskets can fail.
This is only from stuff off the 'net mind you and of course, no two engines are the same.

Any idea where I can get a 125T motor, Sully?

Not in terms of complete runners, but between myself, Skunk and AJturbo (though he might need one too

) we could get one going out of our collection of bits, we are short of exhaust valves though(first ones to bend)
I shall make some inquiries.

**nudemetalz** · 22nd January 2008, 14:16

Cheers. that sounds great.

Bending exhaust valves ?
I raced mine (back in '93-94) a whole season revving 15500 to 16000rpm without any valve float or head issues.
You guys rev yours higher than that ??

WTF, are you sure your tacho was accurate?

If not did you have some very trick valve train bits?
I don't know what the terminator creator (John Conner) gets his one's to rev to but I'd be interested to hear, Speedpro can you shed light???

Mine falls flat on it's face at 11500 as it valve bounces, with a basically std valve train.

If that's true it must have made the most heavenly wail at those revs.

Shuffles off comtemplating new valves and springs

**F5 Dave** · 22nd January 2008, 15:38

Yes I remember Murray the MB50 guru at the time I started racing used to rev his MB50 to 17000 he told me. I learnt from experience that anything over 12000rpm would lose the ring tips & the power would fall drastically. He had some silly little tacho on it so obviously believed it. The std tacho went up there too (or rather an inch past 12000) but it was lying worse than an 07 R6.

The next tacho I put on was later used on the dyno & proved accurate hence I know what revs it really did.

**nudemetalz** · 22nd January 2008, 16:14

Okay, maybe my tacho had some '07 R6 going but it was stock and I had to turn it nearly upside down so it could be read !!!

I must confess I did have some heavier valve springs in...can't quite remember what, might have been XR200 ones.

She had a 2:1 and yes it did scream alright !!!!! Heavenly noise too !!!

Not sure what John's 125Ts rev to but it is pretty high. He has two cam grinds - sprint and just fast. The problem he has is if revved tooooo hard a rocker breaks. I'd guess they do over 12,000rpm. He programmes the ignition boxes as well so ends up with a very wide powerband with the optimised ignition curve.
