Does anyone have a front CR250 motor mount sitting around for an Anderson Maverick? One side of mine broke and I thought I’d check before having another one made.
Hi Mark – can you take a photo of your existing mount and post it – that will enable me to check and see if I have one floating around.
I’ve tried to post some pictures, but apparently I need a publicly viewable site to post them so the URL can be referenced. I thought this had changed with the new forum. I don’t have a public site for posting pictures. If you don’t mind PMing me your email I can forward the pictures to you.
There is a pic of both Case Induction (taller) front mount, and cylinder induction (shorter) mount here…
A little past half way down.
Thanks Dan. I have case induction motors, so I’ll need the taller one. It looks like someone modified the shorter version to work which may explain why it broke.
I’m thinking that most things mounted to the smooth running CR250 take a beating to the point of failure over time. 😉 Still the best option for competitive 250 superkart racing with more than 2 entries IMO. My current mount (about 10 years old) all but came off of the chassis in pieces. That’s not too bad of a life cycle considering the abuse.
I personally like the shorter mount better to keep the engine lower in the chassis….but the carb angle pretty steep in that position. I’ll be trying the lower with my case ind. project using a floatless pump around arrangement first….if that proves to be unsuccessful then I’ll raise the engine and use my Dellorto.
Dan – I have a pump-around setup and was experiencing the engine cutting out in corners all last year. After trying several solutions, someone suggested it may be that my motor/carb angle may be too steep. I am going to try pulling the pump-around system this year.
As I don’t want to cut my sidpod for motor clearance, is it possible to fit the case-induction CR/pipe under the sidepod with the longer case-induction mount?
I have yet to fit the case induction mount or engine to my kart but I suspect it can be made to fit beneath the pod. I have only used the pump around arrangement on my cylinder reed engines with no issue. I plan on buying both the taller mount and the shorter mount to experiment with. The taller mount appears to be about an inch or so taller so I should be able to compare carb angles and exhaust clearances. Maybe Ian will chime in in the mean time.
What pipe are you running? I am using an older Anderson/Viper 2 piece pipe that can rotate around the header and at the center of the 180 deg bend So it should be able to be adjusted to adapt to the engine height change.
Ian indicates that the taller mount will allow the Viper pipe to fit under the sidepod. He is sending me over the new mount so I should be good assuming everything arrives in time for NCK’s season opener on March 28th.
Thanks for the responses everyone.
You can’t see the longer mount, but it is in there. It is tight, but you have about 3-5mm clearance when the exhaust is fitted properly.
