Not needed as long as you have resistor plugs and caps.

Thanks, I will get resistor plugs for it and I think the caps are resistor but I will check.

You should be running race plugs in a race engine - fine wire Iridium/Platinum R7262, stronger spark, more power + 1.5 Hp in a SKUSA CR125 over a BR10EGV.
And use the blue NGK Jetski caps - way more reliable than anything else.

Always used those as the silicone absorbs damaging vibration and water resistant by design. Electric Blue colour? Sign me up.

I all ready use the blue NGK caps - the best I have ever come across. I will look into getting some R7262's. Thanks

Hope they switch away from those Airsal cylinders...two Bidalot 50cc incl. their pipe and you are looking at close to 40 rear wheel HP out of the box.

do someone know these guys? i can probably provide a far better 50cc cylinder for them

I am picking one looks like this...

Nice work, I'm curious to hear the improvements from the intercooler. I suspect if you were at 100deg IAT it will be significant.
Speaking of gearing, what size rear sprocket do you run?

and the other this...

I have ordered some of these open tip EGT K type probes, I will let you know how they go:- https://www.aliexpress.com/item/1005...Cquery_from%3A

Nice work Kyle. Recognise that section of road presumably by Glen's.
Hope it is smooth enough else those engine brackets may need some more support.

Racing this weekend, be finished by then?

Be down to budget. Mostly. Get it running first.
Rules (don't start us on the rules) imply should be based on road type engine or at least not use competition engine or parts. Cylinders mimicking road spec are closer to intension. Use of fzr parts etc help case.
You could argue all day.

Rotary valve conversion and AM6 50cc cylinder on a Suzuki RG50 bottom end.

It will have a long rod and I am going to retain the cavity left by the case reed. I want as much crankcase volume as I can get.

If I can find a Benelli 250 bottom end I might be tempted to build a 100cc twin too. Those clever engineers (I am very impressed, even a little jealous) can't be allowed to have it all their own way.

AM6 cylinders have 56mm stud centers, the same as the 70's Benelli 250 twin. The 250 is just an overbored Benelli 125 twin. So the gearbox is light and ratios close, perfect.

Currently we have a Suzuki RG50 Fitted with a RV and 70cc bored out AM6 cylinder making 24rwhp. So 100cc twin using two AM6 50cc cylinders might be pretty interesting to play with.

I need a two stroke 1970's Benelli 250 twin bottom end or complete engine. Condition, not that important. If anyone locally in New Zealand has something they would sell, please PM me.

I'm searching around trying to find these blue caps, only thing I can find that night be it is discontinued. Any chance you have a link or a part number?

AM6 and Derbi d50 have 52 mm space pattern, 56 mm is Derbi EBS.

I am Sorry. I do not have a part number , I just get them form the local Yamaha Shop.
