Pacemaker question?

[alanscottj]

Just got myself an early Li150 pacemaker on good old fleabay. Anyhow, didn't realise there was an early and a late model, I realise there's some concern over the third gear, particularly in high powered engines. Some say they are ok some say not. I have two scoots, one is a muggy 186 in my series 2 Li, that needs a box and I am about to do a ts1. What's your thoughts on using this box on either, given that I am not a racer, I am not in the habit of thrashing scoots.

I have a 200 casing arriving tomorrow for the Ts1 build and have the choice of a GP200 box or the Li Pacemaker to put in it. What's your thoughts on this?

Many thanks

'64 Pacemaker internals transferred into a large block casing and 15 years of abuse in a highly tuned engine without a problem !
Personally never seen a broken one yet.

Would yours be the early with the 'weak' third cog?

Yep and measured to verify.

Just to balance the argument.
I had one in my ts1 200
now missing seven teeth on the third gear.

Tbh it loOks like I'm going with the Gp200 box in the ts1

On the up side I run one in a 175 stage 4 and its fine.

I'll make use of it somewhere, I have some old 150 casings with a 175 top end, might stick it in there

I've seen a few break over the years, but as you say it not only down to the power of the engine, how it's ridden is a much bigger factor.

I've broke teeth on strong LI150 Spanish boxes qhile on track but had the gearboxes last thousands of miles on the road.
