hello chaps, i'm back again lmao, had a few issues this end and been a tad off with rc for a while,
anyways, has anyone had one of the rovan 45cc engines?
if anyone has, what are they like? i'm tempted to grab one and see what can be done with it,
ie, porting etc,
also what are boosted pipes like? they any good?
hope all of you are well and keeping healthy(y)
 
thanks for that sean (y),
and yeh its a rovan :LOL:, i would ideally like an rcmax, but the cost is a tad high at moment, the engine is for a build i've been planning for afew yearsnow and finally i'm in a position to gather a load of parts together, but an rcmax would put a massive dent into the parts budget :LOL:,
i think i will go the rovan route and strip and rebuild/ port match etc etc,,
then i can always upgrade the engine at a later date,
the build is gonna be a true one off, so need an engine and pipe to build around from the getgo,,
 
I took a 32cc Rovan and put an ESP race ported top end and new pipe on it and so far it runs great ! seems to have about doubled the power . I think the bottom ends on them are gonna be fine but time will tell. Bottom ends are hard to kill in my experience.

Oh and check the SQUISH on it , my stock Rovan had 0.055" , with the new head I used NO Cylinder gasket and got it to 0.022"

yeh thanks buzzkill, its the 45 i'm gonna have a go with though mate,
yeh still rovan but just the larger cc engine,
i aint seen any head kits for the 45 yet , not sure whether anyone will or not tbh,
and yeh i've seen theres squish issues and just general quality probs , been having a proper look online for known issues etc,
bottom ends will be fine as ya say , just the top ends seem to be the problem,

Every Bartolone Racing engine is built and checked by Chris to his high standards. Each engine is checked for proper squish clearance to ensure that your engine provides maximum performance and reliability.

  1. Bartolone Racing 45cc Billet Reed Case
  2. Precision 5-Axis CNC ported Cylinder
  3. Windowed Piston
  4. High Quality bearings and Reed Petals
  5. Low Profile Reed Block for the most clearance in vehicles
  6. Professionally Assembled by Chris Bartolone
  7. Every motor is checked for proper squish clearance
  8. Compression is set for maximum performance and reliability
For $700 ? might be worth a run
 
I'm sure it's a good motor as Chris is a known builder. but I just have a hard time trusting those cylinders and such. Seen too many pictures of nikasil flaking off and such. And the rovan I had, the crank had like 2mm of rod play . Id rather spend my $$ on a zenoah that I know is good ?‍♂️

Im sure he would NOT put his name on it if it wasnt good stuff , I would'nt , your rep in biz like this is everything. From what I have heard Rovan has made improvements lately but I am new to these motors so ??

i get what ya mean about the top ends z,zed,zee :LOL:,
but need an engine to get me started if ya get what i mean, can upgrade to rcmax at a later date when funds allow,
and yeh the nikasil flaking etc, but even zenoah had nikasil issues at one point,
sooooo, probably get a stock one and strip, port match and make any other mods thats needed etc, then see how it goes,
engine and pipe needed to build around and make sure everythings gonna fit in there,
cash saved on the engine will be used for parts for the build, just ordered a really good quality set of 10mm tube benders,
then will get the engine/pipe ordered and then get some driveline parts ordered etc etc (y)
