About quality and texture: I am happy with the quality of the 143cc e Stage big bore kit from SP Takegawa. The cylinder is aluminium with a steel sleeve and the piston is cast from aluminium. About the feeling of use: With the small increase in engine capacity and also an increase in compression the power the engine produces is now much more fun for around town. Products to buy together: The N-15 camshaft from SP Takegawa would also be desirable to purchase alongside the e Stage 143cc big bore kit as one is not included, this will help to continue producing more power in the higher RPM's then the OEM Honda camshaft. Difficulty of installation: The process to install takes about two hours and that includes checking all the ring gaps with no adjustment required before assembly. A little difficult to do but the Honda service manual has all the information to help you get the job done correctly. Cost performance and comparison with other products: Good costing as you are getting a high quality big bore kit at a very reasonable price. Much cheaper then the 181cc kit and requires less supporting parts for a reliable engine. About shipping and packaging: Sea frieght is my preferred method of shipping due to the lower cost and it is fantastic that it has returned as an option once again so I can put my money toward parts and not high shipping costs. Webike kept me updated on the status of my order up to when it shipped. The parcel arrived within the expected date range and was well packaged with no chance of the part being damaged. Any concerns, cautions, or advice when purchasing: If you are looking for a simple tuning option then the SP Takegawa FI-Con is what you want and if you are looking for the best tuning option then the aRacer Mini-X and AF2 is what you want but not currectly available from Webike.

About quality and texture - Top quality. All the items included in this kit are perfectly finished and I did not have second thought about fitting it to the Monkey.About the feeling of use - With the 143cc kit fitted the Monkey is now more usable around hilly areas and I feel more confident riding with traffic due to the increase in bottom end performance.Products to buy together - A big bore kit will not operated correct or last very long without the addition of a fuel controller, so that is a must product to also buy if you intend to install this 143cc kit. Webike have many different options to choose from.Difficulty of installation - I find the piston and cylinder change on these Honda engines is a fun job if I break it up into a few parts. First I like to build up the new 143cc kit making sure everyting goes to plan, then remove the old parts and install the new ones and finally carry out the inital starts to bed in the rings before beginning to ride the Monkey again.Cost performance and comparison with other products - I love how affordable these motorcycles are to maintain and modify. There are many different big bore kits for the Monkey and from the smallest to the largest the prices are not so different but with the larger ones you will need to buy a lot of additional parts. If you only need a little more power then this 143cc kit will make your whole build cost very affordable.About shipping and packaging - Sea freight is my preferred shipping option and usually arrives in Australia in 6 to 8 weeks from dispatch. Always well packaged to ensure parts arrive safety and are ready for use. Any concerns, cautions, or advice when purchasing - Before you jump in and buy any big bore kit, do yourself a favour and research what extra parts you will need and Webike will more then likely have most of then and at a great price too.View Detail
