Author Topic: New ESR motor running great (Read 6824 times)

Just got my new motor in and live it.
New 310 ESR cylinder ported by Neil (thanks Neil)
New ESR cases, clutch cover, stator cover
New Hot Rod crank and seals and bearings.
Started out jetting fat with all new electrical except CDI that was my spare Ricks cdi
. Motor started up second kick and sounded good. Did about three heat cycles then rode around the yard maybe quarter throttle for five minutes. Was running a little hot so checked everything and found no problems. Made several more runs like this and was still too hot for my liking 200F. Didn't feel like it had as much bottom end power but I blamed this on the jetting. Got a OEM cdi and it made a huge difference. Temp dropped to 180 and pulls hard with plenty of bottom end power. Almost like a four stroke. Sure I will be going up on my gearing soon.
Thanks again Neil for an awesome port job. Better than I expected.

Good to hear it's running well! Love how the ESR stator cover has recessed bolt holes. How does that stick-on temp gauge work?

When cold all black. As area heats up each progression turns green to yellow. Easy to read

Do you have an in-line water temp gauge?

Just have a stick on temp sticker. I know it's not dead on but it gets me in the ball park. Used them on several applications and they seem to be close.

i see about a 20-30 degree varience between my tape guage and the inline temp gauge. tape being higher. looks real nice my son and i love our 310.

I am looking at doing almost the exact same build but maybe a little larger cc. Can you give us a round about cost for everything with the cases, crank and any extras. About how long did all the work take to get done? If you don't want to say publicly, can you just PM me.

Thanks,
Mike

Very nice. Enjoy.

The motor looks sharp. Glad you are enjoying. Yep, the ESR 310 is the best bang for the buck when it comes to bumping up the power over stock. Great platform to build off of.

That does look very good. Very clean but bold look.

Very nice motor. So happy eddies cases have no issues, & we can keep our 250rs going even when Honda refuses to keep making parts.

Not to derail the thread, but I recently came across ESR cases and I was wondering if the ESR standard cases were compatible with all OEM Honda parts.If not,is there any alternative other than used OEM?

huntertools · « **Reply #14 on:** July 07, 2016, 05:07:36 AM »

All transmission, clutch side components and counter balancer are OEM parts. Crank is a Hot Rods. Cylinder, clutch cover and stator cover are ESR but OEM will bolt right up. No issues what so ever putting this motor together. Would highly recommend to anyone needing cases.
