Research @ YamAHA REVEALED that keeping these high performance machines in the RED line constantly 4 more than 15 mins to hAlf an hour flat out all the time without a break can destroy any high performance 2 stroke. It's even written in some TURBO 4stoke bikes and cars(written in the owners manual). After each flat out red line run for 15 mins, close throttle to run slowly, mid speed(speed limit)- or stop and take a brake. Nice vid, hope the owner learned a lesson. !!!!
Hey Chris i got the bikes home took it for a spin and she runs great every thing sounds like new you have done an excellent job. even the rd400 is running great. Thank you great work
Try get the original airbox mate , much better than crappy pod filters ,I can hear she's a little boggy low down. A skimmed/lightened flywheel really helps the engine spin up quickly too, but get the bike to run right first . Lovely bike !!
Very nice bike built with very nice parts I just take longer to rev the engine past 6000 rpm only after 500 km and I put 1% mix on the tank for the 1st 800 km. I also avoid constant engine speed. Anyway nice work
How I know this: I was the head Technician 4 Droomers Yamaha Racing In Cape Town, And Johannesburg, Sout Africa...re From Cosworth Engineering Nothhants....
Not sure I would be revving out like that on fresh bores tbh, as a carefully run in two stroke engine will almost certainly have a longer life expectancy. Still a good upload though.
@@dccsound9209 Hey mate, after every rebuild I’ve done I have said just ride the bike normally don’t go and ring its neck down the quarter mile to see how fast it goes. Do a couple of heat cycles gentle rides get some kms down and it’s a 2-stroke they’re made to rev just don’t abuse it! Enjoy your ride 👍
That 350LC is really beautiful. Wished I had bought one when they first came out. - that example is stunning
Had 4 back in the day,all in different guises,love to have another,i wish this was smellyvision!
The owner will be happy with that, I'm sure. Good parts, top workmanship, nice re-set back to zero K's on the motor. Nice work.
I had the same bike back in the day mine was very special iv never stopped liking RD I all most bought a 500 nice bikes.

I take it you gapped the piston rings and chamfered the upper and lower edges of all the ports in the barrel after having them bored ?
After a full crank, rebore new piston build what would be your running in recommendations. Just had one done and slightly nervous

Those bores look suspect!. LC bores always wear unevenly and Never clean up at 0.25mm increase, if bored properly.
