That's the best breakdown I ever had on this thing.
Yep thats a very important item to check before leaving home.....LOL

I have an engien on my bikes so I dont have to peddle unless I want to, so checking the fuel level is very high on my list of things to do before I leave out for a ride......

Glad to hear you got that engine remounted up and in good shape....


Peace

I have oly been building high performance 2 strokes for 30+ years. I pressure tested this engine and sealed the crankcase before installing it and replaced the crank seals with good quality double ribbed seals. I havent hooked up the tach but I can tell you it is a strong 8.5-9K RPM if not higherr and falls right back to 800 idle...

Thats very cool,

I'm fairly new to the 2 strokes, I've build several pretty solid 4 strokes in the past, but I still have a lot to learn on the 2smokers, built my first engine about 32 years ago myself so I been tinkering with lots of this junk for many years, I had an uncle that set some records on the old Yamaha RD's back in the day, but I was too young & unconcerned at the time to remember all the stuff he said about the engine work he did back them, he owned a Yamaha deakership here in Texas at that time, but He's passed on now so I cant ask him about any of it.

I wish I would have been older so I could have learned more of the stuff on the 2 strokes like you are talking about, I sure could have used it now while tinkering with these china girls.

Keep us posted on your results and post some pics too if you can, I know I am very interested in your project and wish you the best of luck with it.

Peace

I securely mounted the Tanaka three-piece expansion pipe onto my Tanaka 47R engine. I love how the pipe curls over the bike's top tube and back under the down tube to end near the carb's air filter. This pipe also allows the OEM Tanaka muffler to bolt onto the pipe's silencer. This should make it much quieter than stock, which is very loud. All I need to do is wrap some heat protection around the silicon exhaust tubing near the expansion pipe. This 39" hose connects to the OEM muffler and runs past the rear axles.

After I mount the Happy Time four-liter fuel tank on the rear rack, my motorized bicycle will be ready to roll.

Previous top speed is 40+ mph. With this new pipe, I'm expecting 45+mph at 8,000rpm.

Angry Re: what did you do to your motor bike today?

Today?????????????? I spent the same as the last week trying to get a new 48cc silver slant sky hawk with the new junk carb to run other than just idle, chasing air leaks and still getting no power and a super boggy motor cant even ride it!!!! I think kings gas motors needs to re up date there so called new carb and replace it with the old style. I am going to remove the carb and install a old one to see if it solves my dilemma !!!!!! Cant get any help from KINGS

kings is the same as gasbike.net (i think) good luck trying to get any type of help from them

also i agree with that carb the new (CNSv2) carb is s*** get a NT or a SPEED carb. simple design, not much that can get screwed up on it.

Nothing much, worked on the tank a bit. Waiting for parts to get here but the SBP M6 1.00 head stud set is here already.. I ordered on Friday. Some of the stuff I ordered was shipped today. Guess who I'm going to try to order from when I can?

The 3" coupler collar I needed for the tank arrived. Waiting for a few small parts for it, too, then I can get on with that build. Should be about 10 pounds of copper when it's done... I look at it this way; if I break down somewhere I can sell the copper

Did the Starbucks/ grocery store for a basket of stuff thing with the 50 slant-
went out a couple days ago with the 66- 36 sprock NTSpeed carb on the newer short billet- and thought "This thing is just too fast!"

the 50 slant with the old carb on sleeves is running OK but not great- not really broke in I don't think- but the pedal even seems harder- Did I get something older than needle bearings ? don't know

anyway, it didn't like to get shut off, like I always do at long lights- and it was bogging down a little the last couple of miles- I wonder about the mix. I'd like to put my older billet intake on, but the studs are different spacing on sleeve carb and I'd have to redrill the billet-

So I though about getting a bigger carb- I'll be patient- it just isn't getting out of 4 stroking much- but has run fairly well.
