what tends to break on the HT engine?

do the cylinders just wear out, when you beat on them? or do they break rods?
I definatly hear more piston noise from mine durring warm up but not so much when its hot
I was thinking of putting an iron sleeve in one if the bottom ends are pretty bulletproof
Ive spunn the crap out of mine & it seems to be hanging tough but the rod & wristpin seem pretty wimpy
thanks for your input
take care

The only thing that has broke on my 'vintage' kings motor was the cast intake. He sent me another 3 weeks after emailing him about it. In the meantime I got a chrome one from Dennis Foster. I'm now over 3200 miles, and it's still going strong. Wish I had bought 3 or 4 of his kits 4 years ago!

thanks for the input :-)
I like my HT too
I have another bottom end coming that I plan to ballance (winging it) my only problem with the engine is the lack of balance
more what I was getting at was when you rev them really high what tends to break?

Owner's patience from stuff vibrating loose.

yeah. Patience wears thin after a couple of times of going over every bolt. But it's worth the hassle just so you don't go over the bars. Checking the bikes bolts also help.

Loctite and USA made nuts, bolts, and studs are the way to go. I also use locknuts even on the hot stuff and double nut whenever possible.

Loctite blue and red are your friends (after warranty periods). I have a bike right now that has over 500 miles and nothing has fallen off.

If it ain't broke, and you mess with it long enough, it will be.

I've seen some scuffed cylinder (more than likely due to cold seizure) and wrist pins that were very worn. One grenaded needle bearing engine, and beyond that, any prudent operation will more than likely need only rings, maybe a new cylinder/ring/piston set.

They aren't racing engines, or anything even remotely associated with one.

how are you going to balance it ? there is only one cylinder these motors are counter wieghted to keep your reciprocating assembly wound up and give it enough velocity to push the piston back to the top of the cylinder when on your compression stroke. i have lightened the piston and pin considerably results = less vibration quicker revs. please post ideas on how your balancing it.

Hi , I too had a Kings 70 and all was well with it for many a mile until the chain broke and jambed in the front sprocket housing and broke the engine case. It was the strongest running of any of the 5 H Time engines I've had over the last 4 years. The one with the most miles on it is the Dax 65cc that has bushings . I do run it with alot of oil in the mix but it has over 2 k miles on it and still runs as strong as ever.I have learned over the years the the HT quality is poor and the engines are not to be expected to do any more than a putt putt putt around town . Not for performance in any stretch of the imagination. I'm looking for a quality engine that I can abuse and that can take it or be built up to take it. It's come to the point now with my bikes that I tend to go slow and putt around cause I'm tired of braking the things and or going sailing over the bars. Tom in WV
