ESE's works engine tuner

Had a quick look at Tillson a while back but not much jumping out.

That first picture with carb on engine would make me concerned Husi. I think you are not going to have space.

MC28 looks good. Or is it MC21?

21 i guess... Rob will know for sure.
There is plenty of stuff about them on the NSR.com site. Apparently some are better than others and they flow real well for what they are.
A mate had a huge Pumper off a Jet ski on his MB100 and it worked real well. But over fueling on over run was a issue Kart track hairpins were ugly and dangerous when it chimed back in)
but i think i had sent Rob some stuff Jennings did to cure that with the 34mm Macullochs on his 350 Kawa twin.
Yes the inlet looks a bit of an issue with the rear mount.......I will have to wait and see........
Maybe Fletner could cast me up a set of cases to fit the CVT, 100cc Aprilia "like" cylinder and through in a variable disk

How much carb do you need, this is a racing Tillotson with remote jet adjustment.

Yea .... na as they say, but if your serious about power, an old slide carb could be worth a look.



They are typically 28-32mm and the pumper parts look like Tillotson so should be easy to get.

[TZ350]

21 i guess... Rob will know for sure.

No not sure, as I went through a phase of buying a lot of different carbs off the net looking for a way to get the best from the 24mm rule.



In the end I got my best results by modifying the humble 24mm OKO. They are so easy to hold in the lathe and machine, there is lots you can do with one of these.

Unfortunately not much use to F5 Dave.

I am coming to Auckland this weekend for the final round of the Kart Champs, so i will bring the NSR engine and parts with me.
Mat Hamilton can bring it back down to CHCH in the big VW van with the karts.
If you mount the engine well in your frame Husa, you can delete the top mount altogether, look at Chambers RG50 - giving plenty of room above the gearbox for a dead straight inlet
with RGV carb.

One other point here as well - I have been waiting for 6 months to get a shipment from Ignitech, they wont reply to my emails and I have 5K worth paid for and pissed of customers.
I rang Jim Lomas in Czech to get him to talk to them, but no luck - yet.
Anyone know someone that speaks Czech.

[F5 Dave]

That's not good news, I'm squireling away $50 notes (ok I'm about to put the 2nd one in) into a box in the garage so I can't spend it, & selling stuff to buy one for the 50. Maybe when I have enough you'll have got the shipment.

Try calling them, must be someone who speaks Engrish there.

If I had that much spare for a carb I'd be buying a Smartcarb for my GasGas. Not that they haven't had some teething problems.

Hope you get what's yours.

That would be ubber cool.........
I have League over there on the 12 and 13 OCT. I think the BOB is the following weekend.But i am sure i can get over there to pick it up before that anyway.
I hardly speak English. So no help with the Czech sorry...
I will have to look at chambers one. The Frame i have has been modified for a YZ250 or something.

I guess this is how you mean.

And the one I liked most of all, a RG50 in a Honda RS frame. One of F5 Daves engines fitted by RMS engineering.

The RG50's rear engine mount slotted straight into the RS rear mount and the front RS frame mounts used simple brackets to hold the front of the engine.

It also used a light weight hydraulic Mountain Bike rear break with a thumb operated master cylinder on the left handle bar, very clever.

[F5 Dave]

Yes chop that top mount off. Here's my RG/RS with one front & one rear mount. You can see where the frame comes forward at the back but there is room to spare on the 50, but the shock is close to the top of the carb & carb to the cases.

[husaberg]

Well I sidestepped the shock problem with the Case reed conversion (as long as the carb isn't too tall). Only problem is you need a smaller carb than the KX & ideally downdraft like the RGV Mikuni. FCRs are huoooge 'case they don't care about minimising the area under the carb on a foul stroke.

Grumph mentioned these a while Back i hadn't seen them.
Mikuni TDMR
This one is 32mm obvious for a Foul stroke but i guess they can be made to work.as lots of the Mikuni stuff is interchangable


It looks like Mikuni do a 34mm version of the BN pumper off the jet skis.$147 US new here
Which i am sure is what my mate had on his MB100.

Put a throttle body on it, don't bother with the carb. Throttle body much more compact.

The F9 is losing it's EFI, a backwards step. Seems it's not in the "spirit of the era" if I want to keep racing it in VMX. Fair enough, we will teach them ( VMX pre 75 ) a lesson in how to hot up a rotary valve engine even with a carb on it. Out to the pattern shop to make up a new barrel with modern porting, eye ports etc. More than one way to skin a cat, apparently.
I'll show them " spirit of the era"!!

i don't see the need to make a complete cylinder the bighorn cylinder will modify quite nicely. What your bike desparately needs is a good pipe ....................and some proper shocks

[Yow Ling]

Hey Dave would one of these do the job ?

[husaberg]

Hey Dave would one of these do the job ?

shhhh........Just don't Tell Dave who owns Keihin (or Showa for that matter......)

[F5 Dave]

I'd love to try one for size, perhaps when I'm down for the BoB. If you south islanders are still talking to me after I win the race.
