I get the slight feeling you may be a rotary valve fan TZ? Spotted a pic of these outboard reed valves and was amazed, I forget bikes aren't the only things using these engines, and that some of the other applications are on a much larger scale than the tiny things we are playing with.
Will you use an external reed block on your new RGV/TF engine?

Yeah that's the same type of reedblocks I'm using on the MB, but I'll have to use at least two braces of them.[Tui add]
Funny talking about R/A grinders. I was just thinking last night that I wish Dremel had made a mini RA flexidrive doofah. Well I went to replace my Dremel yesterday (I have a large Bosch grinder & two size air grinders which are nice, but sometimes for a quick job the Dremel is easy), anyway my old one is rattley after 20 years of hard work, so I buy a new 400 & notice they have a RA tool for 50 note.
Hmm, pretty big, oh & then the bits have to go in. So I'm holding it wondering if I could strip it down & spot weld a bit right close to the bevel part. Ahh sounds like a drama, must go see my mate with the dentist tool & see if I can persuade him to sell it now. Problem with the dentist tool is they have tiny bits & no torque. Great for correcting corners and defects, but not much else.
Don't you look at my accountant.
He's the only one I've got.

Rick52 rode the wheels of his new bike and won or placed all day in "A" grade.
When the bike was run up on the dyno it was found to have 18-19 rwhp.
Comparison of Rick52's 18-19 rwhp with a Team ESE bike.
Sunday showed how talented Rick realy is and if he ever builds up that GP125 engine he has in the ESE style and gets 27+ rwhp he will be very dangerous and the 4-Strokes could prety much kiss it goodby at Mt welly.
Was worth a crack
What was evident from the sidelines on Sunday was how much quicker Rick was entering the corners, every corner!Originally Posted by TZ350

. . . peaking at 8700. so not a rev monster then
'cmon Chris (RMS) run a riffler up there.

Fantastic work team ESE. Love watching the development.
Time to (be the second to) crack that 30hp mark!
Forum whore
I am hoping to be the first, to post a dyno graph of 30+ rwhp from a bucket..........
Forum whore
After 40+ dyno pulls at near 30hp the glue blocking the oiler holes is still there inside the piston..

Tried one of Chambers pipes that he designed using Blairs formulas and it made 29 rwhp so not bad for a pipe design from a spread sheet. The Spread Sheet can be downloaded from page 200, post 2988.
The plan is to raise the transfers from opening 116 ATDC to 114 for a litte more Transfer Time-Area.
The first step is to find 114 ATDC with a degree wheel.
Then use Marking Blue and a Scriber to set the new Transfer Port height.
Ports marked out. The cylinder has garks from my porting work and had done a turn on some road bike before being purchased on Trademe and it still makes good power, will rebore it when the experimenting is all done.
Its a gamble rasing the Transfers as that will reduce the Blow Down Time Area. But I am betting there is a little blow down to spare and its the short Transfer Time Area thats holding it back and a little more will phaten up the lower part of the blue lines Torque Curve and hopfully crack the majic 30 too.
Race it don't store it !

Cheers fellas your making me blushThe new bike is 30kg lighter and has more power much better brakes and handles like a dream !If I didn't get quicker with this bike I should be just watching the racing...I need to ride this bike better before getting more power I think ..Better ignition from a Cr85 next and a engine strip down re-build ...

Man after our battles at Taupo I was thinking it had more power than that. When you were coming out of the corners there was no way past. It just took off.
Thats it I am officially on a diet bike to.
Scuse me while I vomit.

There's enough metal there to widen the main transfer ports toward the exhaust port - more time/area but same blowdown

Cool pic, got me thinking of this one...I get the slight feeling you may be a rotary valve fan TZ?

Thats some serious reed area!

Good tip, I will give that a go first, also I will elongate the Ex side port tracts like you suggested before, too.

I would be a starter for a RG125 engine, any condition, if I could get one, so if someone has one they would sell please PM me.
