Nice RD! What model year is it?
That would be nice, but I doubt that anyone could get a two stroke to pass the emissions tests.
Howdy. It's January 81. The 80 model had problems with the header cracking at the inlet so they reinforced them and added engine bracing underneath for the 81 model.Nice RD! What model year is it?
Also, one of the manufacturers figured out how to do direct fuel injection for low $$$ via the transfer ports. With a bit of luck they might come out with some new bikes for the old-guy two stroke crowd.
My uncle, (turning 70 this year) is the original owner of a 1971 H1-500 Kawasaki Mach III which he bought new in 1971. He traded a 1967 Triumph 500 Tiger for it. I think the retail price in Canada for the Kawi in 1971 was either $1095 or $1195.
I rode it once or twice and it was pretty ordinary below about 4500 RPM, but above 5K - HOLY SH!T
The noise from below the tank became alarming, the front wheel started skipping off the ground and everything behind me...simply...disappeared in a cloud of dense blue smoke.
It was truly, a wild, uncivilized machine that lived up to its reputation as:
Don't get me wrong, it's not that I didn't like the H1-500 - but I had traded my Uncle Dave a ride on my 1979 Suzuki GS850G shaftie (a big, heavy, smooth, powerful, torquey, cushy tourer with excellent triple disk hydraulic brakes) for his H1 - and it was quite a shocker.
- a very peaky 60 HP engine;
- in a 30 HP frame;
- with 12 HP brakes.
Anyhow, he still has it, and he rides it a few miles every year - and it has never been wrecked, rebuilt or dropped.
Well got the oil set just right, Hardly any smoke once warmed up a bit. Pulls much freer in the higher gears and revs higher aswellin my experience that adjustment has to be Right on the money.... make sure the throttle cable is routed properly so the casing of the cable has some slack in it before adjusting the cable.... and those split cables could alwayse mess up... the thick end of the cable could get above the plastic slider and give you trouble that way too.... if the cable seams too short that is probably the problem !
.....
I spent hundreds of hours porting and polishing 2 stroke bike engines, the ones that showed the biggest improvement were the old DT1 Yamaha 250cc bikes of old... they had a pressed in steel sleeve as the cylinder bore and it did not match the aluminum cylinder ports very well
but you could remove a bunch of metal and make that baby breath allot better ! , Suzuki 250's of the day were very well matched as were Kawasaki 250's but Yamaha's really sucked big time... which is surprising given how well they went ! , the bigger bore machines all matched fairly good I ported and polished my own A2 Kawasaki twin 350cc and cut the rotary disk valve and that puppy would give a RD a run for the money even though it weighed almost 100 lbs more ! .....
I miss messing with the old 2 stroke machines..... nothing like them for throttle response !
You'll know your RD is running right when you can grab a hand full of throttle and wheelie..... no dumping of the clutch needed on them.
heheheheheh
...I liked running the spark plugs ,all my 2 strokes "chocolate brown".... not tan... brown and they lasted a good long time for me! and the carbon buildup was no more than normal that I could tell....
and DO NOT use outboard motor 2 cycle oil in your bike ....ever.... it needs to be for AIR COOLED Engines not water cooled.
.... you'll knock out the big end of the rods using that outboard 2 stroke oil...... or seize it. ( 2 cycle oil for chainsaws works great!)
