That's right folks...My humble, utilitarian Honda crf250l 2015 is about to receive a cbr 300r engine swap. My crf started making strange noises and so I went back into the Oz vendors section to find a thread for a new mechanical business on the Sunshine coast. Drivewell mechanical. http://advrider.com/index.php?threads/drivewell-mechanical-sunshine-coast.1181800/ I took the bike over to Gerard and we had a good chat about what he's done with bike tours in the Far Nth of Australia. I ran my thoughts about some prospective bikes to replace my Triumph scrambler since I was more into exploring off road with the crf than road riding with the scrambler. Essentially the crf while being a fun bike showed its suspension and power deficits when pushed faster both off and on road. So I was thinking of just one bike to simplify things. Is it too soon to insert? ....Buy a KTM...which one? ...who cares which one...ok, ok ... A 500 exc! Ok. Now I've got that out of the way. I did get as far as test riding some used bikes the week before the crf signed off. I rode a Ktm 530 exc, a WR 250r, dr650, drz400e and a Kawasaki klx450r. Funnily enough I got back onto the crf thinking if it had a bit more power and I had the suspension upgraded it would be spot on for cruising around and exploring the hills and dirt roads out the back of the Sunshine coast hinterland where I live. I'm not looking to ride single trail or snotty terrain since I'm doing it solo. I have a large VW van to either wheel it into or put it on the back with my rack n roll carrier so it doesn't have to be a "adventure cargo bike". I can drive the way further afield and use it as my camping base to explore areas if I want. Anyway...Gerard called me with the bad news that the top end was going to need quite a few parts. So while looking for used top ends on Ebay I came across a used cbr300r engine with 15,000kms on it. The vendor also had the ecu, throttle body, coil and spark plug listed too. I started researching a prospective engine swap. Rick Ramsey did an excellent comparison sheet of the engines. http://www.rickramsey.net/CRF250Lresearch.htm To date I've found threads on Thumpertalk where people have swapped various parts and even the majority of the cbr's engine but none have simply done a straight entire cb300r engine swap into the crf-l. So Gerard also did his own research and agreed to do the work for me and document it along the way. I can take the bike to Full force racing suspension specialists (famous now for their plex valve DR 650 transformation) to re-valve my stock rear shock and front forks once the engine is in. https://www.fullforceracing.com.au/ I'm on a bit of a budget. Probably will need a ejk fuel controller down the track too. The crf has an FMF Q4 pipe with power bomb header, standard airbox with K&N filter (bought it used this way) and I've put a 13 tooth front sprocket on it. The engine should leave Dubbo in NSW tomorrow and so by middle of next week the transplantation could commence. Here's the crf waiting for its donor engine.
